Ch.4 Tissues

Question 1

Simple squamous epithelium

Location and function

Answer 1

Location: kidney glomeruli, lining of air sacs (alveoli) in lungs, inner lining of heart chambers, blood vessels, and lymphatic vessels, lining of ventral body cavities (mesothelium or serosae)

Function: diffusion and filtration, secrete lubricating substance (얇고 짜부 된 모양)

Question 2

simple cuboidal epithelium

Location and function

Answer 2

Location: Ducts of secretory glands like pancreas, thyroid, secretory portions of small glands, kidney tubules

Function: Secretes and absorbs (통통함)

Question 3

Simple columnar epithelium

Location/Function

Answer 3

Location: ciliated tissues = small bronchi, uterine tubes, and uterus

smooth = most of digestive tract, gallbladder

Function: protects, absorbs, secretes mucus and enzymes, ciliated cells propels mucus or reproductive cells

Question 4

pseudostratified columnar epithelium

Location/function

Answer 4

Location: ciliated tissue lines trachea and much of upper respiratory tract; stereociliated tissue lines epididymis and vas deferens

smooth tissue in male sperm ducts and large gland ducts

Function: protects, secretes mucus, ciliated cells propel mucus

Question 5

stratified squamous epithelium

location/function

Answer 5

Location: non-keratinized = esophagus, mouth, and vagina
keratinized = epidermis = dry membrane

function: protection against abrasion

Question 6

stratified cuboidal epithelium

Location/function

Answer 6

Location: (rare) excretory ducts of sweat glands, salivary glands, and mammary glands

function: protection

Question 7

stratified columnar epithelium

location/function

Answer 7

Location: urethrae, ducts

Function: secretes and protects

Question 8

Transitional epithelium

Location/function

Answer 8

Location: bladder, part of urethra, and ureters

function: stretchy, distensibility

Question 9

glandular epithelium

shape and types

Answer 9

shape: simple cuboidal

types:

unicellular = goblet cells

multicellular = serous glands and exocrine glands with ducts

Question 10

CT proper loose
areolar

function and location

Answer 10

function: wraps/cushions organs, immune (macrophages), inflammation, holds tissue fluids

location: widely distributed under epithelia, forms lamina propria of mucous membranes, packages organs, surrounds capillaries

Question 11

CT proper loose
adipose

function and location

Answer 11

function: reserve food fuel (triglycerides); insulation; supports and protects organs

location: under skin, around kidneys and eyeball, within abdomen, in breasts

Question 12

CT proper loose
reticular
function and location

Answer 12

function: fibers form soft internal skeleton (stroma), supports other cell types parenchymal cells, white blood cells, mast cells, and macrophages. makes sheaths

location: lymphoid organs (lymph nodes, bone marrow, and spleen)

Question 13

CT proper dense
dense regular

function and location

Answer 13

function: attach muscle-muscle or muscle-bone or bone-bone; withstand tensile stress in one direction

location: tendons, most ligaments, aponeuroses (similar to tendons)

Question 14

CT proper dense
dense irregular

function and location

Answer 14

function: withstand tension in many directions; structural strength

location: dermis, submucosa of digestive tract, fibrous capsules of organs and joints
